Aim of study: In their book Digital Heritage Karol Król and Józef Hernik have made a unique and major contribution to the history of digital technology, and, coupled with that, to identifying the significance of “digital heritage” for societal development, in particular in relation to developmental improvements in environmental processes. The aim of this article is to identify some main scientific, technological, and logical features of the book’s account of what digital heritage is as part of environmental processes. Material and methods: The methodology used in this article is mainly examination of the text of the book, and study of that text’s relationship with extra-textual societal phenomena as environmental processes. Results and conclusions: Results. There are many logical inter-relations described in this paper between the Król/Hernik text and environmentally relevant sources in the development studies literature. There are also many logical inter-relations described in this paper between the Król/Hernik text and certain social science accounts of environmental processes and democracy (in relation to development or progress). Conclusions. This article concludes that the book deals with the history of technology, but that at the same time the book’s text necessarily expresses concern with the present status of digital heritage, and particularly the role of digital heritage in future-centered societal development (in relation to environmental processes).
The aim of the study was to evaluate the potential to satisfy some energy needs of a rural municipality using renewable energy sources. The research was conducted in the territory of the Municipality of Nowa Słupia in Świętokrzyskie Voivodeship, Poland. The novel aspect of this study was to assess current and potential production of energy from renewable sources. The study included consideration of sources of energy such as the sun, water, wind, and biogas of plant origin; and distinguishing actual, potential, and overall renewable energy sources in the period from the time of the study to 2025. The assessment was based on the sum of existing individual sources and also on opportunities revealed in a development trend analysis of these energy sources. Currently, the municipality does not consume energy from renewable energy sources. In view of the potential volume of energy from renewables, the municipality could meet the demands of its residents at 7.6%. The current volume of thermal energy from renewables, it is here estimated that the municipality could meet the demands at the level of 10.3%. In the future, this source could be developed further beyond the present level of 65.8%, which together with energy crop biomass obtained on set-aside land (approximately 70% of available land) would cover 76.1% of the requirements of municipality residents. This article also includes a few more general ideas about sustainable development and energy as suggested by the case study.
